I started a new account on Twitter just to see what it's like. It's completely unusable. The place is filled with shit content that a I don't want to see and bots. Not sure what competitive advantage you are talking about.
I keep hearing this about Twitter and Facebook but my experience is completely different. I believe the default experience is as you describe, but after I started following dozens of retrogaming groups, old games are all I see in both places. Even the ads became relevant and, believe it or not, interesting. I've clicked on a couple, which took me to small creators in the retrogaming and RPG areas.
The For You feed varies week by week but is generally okay. I make heavy use of lists, mute words, etc to clean things up.
X is a train wreck, but an interesting and useful one, depending on who/what you follow.
